Finding the perfect diamond

Boucheron diamond standards

With over 160 years of expertise, the Maison Boucheron takes the greatest care in selecting each diamond in order to offer you the finest stones. Over and above the intrinsic quality of the stone, its value lies in the emotion it reflects. The quality of a diamond can be assessed according to four inseparable criteria known as the «4Cs» (carat, color, clarity and cut).

ETHIC

Among the Maison’s criteria of excellence, that of ethics is fundamental. That is why the Maison Boucheron is committed to responsible jewelry production and sourcing practices. Since 2011, Boucheron has been a certified member of the RJC (Responsible Jewellery Council), an organization that supports and promotes responsible practices in the supply chain. By adhering to the RJC Code of Good Practices, our Company is committed to greater transparency in its ethical, environmental and labor practices.

The 4 Cs

Carat

diamond carat sizes - from 0.20 carats to 4 carats.diamond carat sizes - from 0.20 carats to 4 carats.

The carat is the unit of measurement used to determine the weight of stones, including diamonds. One carat equals 0.20 g. It is believed that the term came from the seed of the carob tree, which maintains the same weight over time. It was used as a unit of measurement by merchants in the gold trade, particularly in Africa and then in India. The carat has been officially set at 0.20 grams since 1906. It determines the size of the diamond, but is never used on its own to determine the value of the diamond. The other three evaluation criteria are also essential. The “4Cs” are inseparable.

Color

The color of a diamond is measured according to an international grading scale that ranges from D to Z. A color D diamond will be perfectly colorless, whereas a color Z diamond will tend towards a strong yellow hue. The diamonds selected by the Maison are between D and G.

Clarity

FL-IF (Flawless and Internally Flawless): No external and/or internal flaws.
VVS1 - VVS2 (Very Very Small Inclusions): Tiny inclusions that are very difficult to see at 10x magnification.
VS1-VS2 (Very Small Inclusions): Very small inclusions that are difficult to see at 10x magnification and in some cases with the naked eye.
SI1 (Small Inclusions): Small inclusions that can be seen easily at 10x magnification and in some cases with the naked eye.
I1-I2-I3 (Inclusions): Flaws present. Inclusions that can be seen very easily at 10x magnification and, in most cases, with the naked eye.

 

To evaluate the clarity of a diamond, you need to look at its inclusions. These can come in different forms (crystal, cloud) and can affect the passage of light through the stone. Diamonds are graded for clarity according to international standards ranging from FL to I3. The Maison Boucheron only selects diamonds whose clarity ranges from FL to VS2 at 10x magnification.

Cut

The precision of the diamond’s cut is the criterion that gives it all its sparkle.

The Maison Boucheron sells only «very good» to «excellent» cut diamonds.

This means that the facets of the stone have been cut perfectly symmetrically to ensure that light is exceptionally well reflected.
